ROLL FOR BEATING-MACHIN ES.

Specification of Letters Patent. Patented Mar, 18, 1919.

Application filed May 7, 1918. Serial No 233,140.

To all whom it may concern:

Be it known that I, CLARENCE P. FoLsoM, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Rolls forBeating-Machines, of whichthe following is a specification.

This invention relates to certain improvements in rolls for beatingengines. More particularly the improvements comprise means for securingthe fly-bars in position on the roll so; that they are held securelywhile the roll is in action and may be conveniently removed and replacedas necessity may require. It is well known that rolls of this characterare used for beating stock or pulp in the paper-making art and that insuch usage the fiy-bars are called upon to withstand a very considerableamount of strain. Owing to this they must be securely 56 made fastthereon. The fly-bars, to be more held in position ina rigid manner andat the same time their replacement or removal must be free fromdilficulty.

The drawings hereto annexed illustrate the improvements in connectionwith a roll and. willnow be referred to in general terms before giving.a more minute description thereof.

Figure 1 is a vertical sectional View of a roll of a beating engine, thesame embodying my improvements. Fig. 2 is a somewhat enlargedfragmentary view of the periphery or ring portion of one of thesupporting frames showing several fly-bars in position. Fig. 3 is a viewpartly in section on the line 33 of Fig. 2. Fig. 4 is a view on the line4--4 of Fig. 2, the fly -bars appearing in section. Fig. 5 is a view ofan end 0 one of the fly-bars. Fig. 6 is a detail view in perspective ofone of the clampinghea'ds for the flybars. Fig. 7 is a detail viewsimilar to Fig. 2 showing fly-bars held in position from both sides, andFig. 8 is a detail viewin perspective of one of the clamping headsemployed for holding each fly-bar from opposite sides thereof, as inFig. 7.

In a more particular description of my improvements similar referencecharacters designate like parts in the drawings.

A beater roll is shown in Fig. 1 thesame comprising a series of spidersor annular frames 1. These are strung or assembled in proper relativepositions on the shaft 2 and particularly described, are united to theperipheries of these frames and when so united the whole constitutes abeater roll. Each of the supporting frames 1 terminates in an annularmargin or ring 3, the base of which extends laterally in an annularextension or flange 4. The ring or rather the flange portion 4 thereofis provided with bolt openings 5 which extend from enlarged openings on'the inner side of said flange 4. These bolt openings 5 lie at uniformdistances throughout the circumference of the frame 1 and the peripheryof each of said frames has uniformly spaced lateral openings 6 whichtaper outwardly on one side and receive the inner edges of the fly-bars7. The two end frames 1 as shown in Fig. 1, re constructed so that thefiy-bar openings 6 have walls 8 inclosing them on the outer sides andforming shoulders against which the ends 9 of the fly-bars a-but whensaid fly-bars are mounted in the frames. The end bars 9 of the flybarsare formed by cutting tlhe ends inwardly so that the outwardly lyinportions 9' of said fiy-bars will extend the ull width of the roll, soconsisting of the assembled frames 1. As shown in Fig. 4 those portionsof the fly-bars 7 that lie within the openings 6 are tapered on one sideso as to have a wedge-like fitting in said openings and the outerportions of said fiy-bars are likewise tapered to a substantiallyknife-like form.

Each of said fiy-bars has oblong openings 10 at points where they passthrough the peripheries of the frames 1. The ends of a series ofclamping heads 11 extend into the openings 10 of each pair of adjacentfly-bars and hold said fly-bars to the frame through other meanscooperating with said clamping heads. These other means consist of aseries of bolts 12 which pass through the bolt openings 5 in the flangeportions 4 of the frames, and the clamping heads 11 are provided eachwith a center openin 13'through which the bolts 12 also pass. uts 14screw onto each of the bolts 12 and clamp the ends of the heads 11firmly against the inner sides of the slots 10 in the fly-bars and thusfirmly hold the fly-bars in position. Each of the clamping heads 11 isprovided on the inner side at the ends with a shoulder 15. The ends ofthe said heads project into the fiy-bar openings 10 and the shoulders 15abut with the adjacent portions of the fly-bars so that the said heads11 cannot turn when clamped bars.

in position. Each of the nuts ii is provided with locking meansconsisting of a plate 16 through which the bolt 12 projects and againstwhich the nut binds, said plate having a turned portion 17 which fitsagainst one of the flat sides of the nut and thereby locks said nut fromturning. Referring to Fig. 2 of the drawings it. would be there observedthat the ily-bars 7 are held each from one side only by the clampingheads 11 as shown in Fig. 6. In Fig. 7 they re shown held at both sidesby a form of clamping head 11 as shown in Fig. 8. This form of clampinghead has the ends thereof reduced as at 18 in order that the ends of twoof said heads may project into each opening 10 in a ll -bar fromopposite sides of said fly-bar as shown in dotted lines in Fig. 7 andthus each fly-bar may be held firmly on both sides. It will be readilyseen that the removal of a fly-bar is comparatively easy while at thesame time the ily-bars are held in a most rigid and-satisfactory manner.

Having described my invention 1 claim:

1. A series of annular frames mounted upon a shaft, fiy-bars mounted insaid frames, the whole constituting a beating roll, said fly-bar havingopenings therein, clamping members having openings therein and shouldersthereon, said clamping members engaging one or more fly-bars through theopenings in said fly-bars, and bolts penetrating the openings in saidclamping members and tightening the same against the fly- Q. In a rollfor beating engines, a series of annular frames assembled upon a shaftand constituting a roll, said frames being or uni- Leer s72 formdiameter and theperipheries thereof having lateral and radial openings,fly-bars mounted in said lateral openings, said flybars having openingstherein, clamping members engaging each pair of fly-bars in saidopenings, bolts penetrating the radial openings in the peripheries ofthe frames and also penetrating the clamping members, and nutscooperating with said bolts in tightening the clamping members.

3. A roll for beating engines comprising a series of rings mounted upona common shaft, the periphery of each of said rings having a flangeextending laterally on one side thereof, flybars mounted in said ringshaving openings therein, clamping members projecting into said openingsand having shoulders which engage the fiy-bars adjacent to the openingstherein into which said clamping members project, and means for rigidlysecuring said clamping members in the openings in the fly-bars.

&. A roll for beating engines comprising a series of rings mounted upona common shaft, the periphery of each of said rings having a flangeextending laterally on one side thereof, the filly-bars mounted" in saidrings having openings therein, clamping members projecting into saidopenings and having shoulders which engage the fly-bars adjacent to theopenings therein into which said clamping members project, and boltspenetrating the flanges of the rings and the clamping members andserving with the cooperating ot the nuts to hold said clamping membersin position.

In testimony whereof I afi'ix my signature.
